rial adapted tc be operated by the armature '2 for controlling contects between the spring members 26 At the rear of the relay is To all whom it my concern:

Be it known that we, Emma It. CoRWI-N and CHARLES A. BALs citizens of the United States of America residing at Chicago, in the county of G00 and State of Illinois, have invented a new and useful Relay, of which the following is s specification, reference being had to the accompanying drawings, illustrating semen *Our invention relates to electrically-open able relays.

The nrincipni objects of our invention are. to provide an improved arrangement of the armature on electrically-operable relays; to provide improved means for mounting the relay as a whole, and to provide improved means for remov' g the coil of the relay when desired without dismounting the relay es s. whoie.

Other objects and improvements in conwhich is suitably insulated from the porstruction wiii be apparent from the followtions 9 and as shown, so as to mount the ing specification. frelu as whole. A hoie 15 is provided In the accompanying drawings Figure through the portions 9. 10, 11 and 12 so that is a. side elevation of the relay or this inventhe screw he loosened from therea-r tion, with the inclosing casing and mounting of the piste 9 and the spool 2 3 one the portions shown in vertical cross-section to coil or coils removed when desired without show the construction of the rele inside of dismounting the relay as a whole. This the casing and the arrangement of the mernconstructic of niiowing the spool the bers extending through the mounting porcoil or coils of the relay to remove; as tions; Fig. 2 is a plan view of i V rewinding or replacportions of the'ineiosing casing shown horizontal cross-section to show the sonstruction of the relay inside of the casing; Fig. 3 is an elevation of the armature-supporting member, showing the details therei of; Fig. 4 is s pi-an view of the por ion shown in F ig. Fig. 5 is an end elevatio of the armature or" the relay; and Fig. 6 is forming a portion of the relay casing, an insulating d insulating the cup-shaped portion 10 from the plate 9, and a second insulating dish 12 niaced within the on?- she i insulating the bar 6 the sun-shaped portion 19. all 0. 133 per ions-Q, 16, 11 and being provided with suitable holes therethrough throng":- which the terminals 5 5 and the rear ends 0: spring members 26 26 extend, whereby th are kept out ofcontact i ti: the poions 3, and 12. The gore e he: 6 by u screw 13 at the e core 3, and the bar 6 is mounted to the mounting plate 9 by a screw ctions 13 18 o the plate 15, thus hinga plan View of the armature shown in 5. 5 ing the armature the notches 13* 19. 7 i v 1 a n 1 :1 I showm the oetans thereof. Lure cnaracoar IS 1. oetween tne extensions 'z .5

of the pie as shown, so as to hold the armature from being raised out of position. The nrmat "r: i" lracted to the end of core 3 when the i W: is energized the armature being normal h id away from the end of 7 pins 8 which are pressed downwardly by the middle springs of the several sets of s ring members 26 26. It will be readiiy seen that w hen the armature 7 is attracted to the end of core 3 the portion 3 ters re er to like parts in the severai figures.

The relay comprises a. spool formed of end portions 3 2 and a core one or more coils 4t wound upon the sooi and having terminals 5 5 extending on: the coil or coils through the end portion 1 of the spool; 21. bar 6 of magnetic material forming a return magnetic path for the core 3; an armature 7 suitably pivoted so as to be attracted to the end of core 3 when the latter is magnetized by current in the coil or coils t; sets the or eture w be moved toward the of spring memoers 26 :23 suitaoiv mounted oar keno to close tne magnetic core 3 and also between of the armature.

circuitat the our '3 on the bar 6 and suitablv insulated from end 0. each other; and pins 8 8 or insulating mateo 18 portion 7" a mounting pi e 9 a cup-shaped portion 10 the said return bar and the said switching mechanism without dismounting the said bar and switching mechanism.

6. A relay structure of the character described, a core and a coil for magnetizing the core carried by the relay structure, a mounting plate, means for mounting the relay structure to the'plate, and means near the mounting plate whereby the said core and coil may be removed from the relay structure without dismounting the latter from the mounting plate.

7. A relay having a core and a magnetizing coil therein, a returned magnetizable member secured to one end of the core and extendi substantially parallel therewith, amountlng plate, means for mounting the said return magnetizable member to the mounting plate whereby the relay as a whole is mounted to the mounting plate, and separate means for detaching the core from the said return magnetizable member without elismounting the latter, whereby the said coil maybe removed as desired.

8. A relay of the character described comprising a core and a coil or coilsthereon, a return magnetizable member secured to one end of the core and extending substantially parallel therewith, an armature near' the other end of the core arranged to close the magnetic circuit when attracted by the core, a mounting plate, acup-shaped portion, a disk of insulating material between the said cup-shaped portion and the mountin plate and another disk of insulating materia within the cup-shaped portion, a mounting bolt or screw extendin through the mountin plate, the said disks of insulating materia and the said cup-shapedportion, into the' said'return magnetizable member, whereby the relay as a whole is mounted to the mounting plate, a pin extending through the said disks of insulating material and the said cup-shaped portion, into the saidmounting plate but being insulated from the latter, whereby the relay is suitably positioned when mounted to the mountin plate, suitable terminals from the said c011 or coils extending through holes in the said disks of insulating material, the said cup-shaped portion and the said mounting plate, out of contact therewith, switch springs mounted on the said return magnetizable member and extending substantially parallel therewith, the said springs being arranged to be operated by the armature and having terminals extending through the said disks of insulating material the said cup-shaped portion and the said mounting plate, out of contact therewith, a bolt or screw holding the said core and the said return magnetizable member together, the said disks of insulating material, the said cup-shaped portion and the said mounting p ate aving a passa e therethrough whereby the last men tione bolt or screw may be loosened when desired, so that the said core and coil or coils may be removed from the relay, the latter havin a suitable casing fitting the said cupshapec l portion to inclose the relay, substantially as described.

9. A relay structure having a m netizable member carrying switchin mem rs, a core and a coil therefor carrie structure and removable therefrom, and an armature for operating the switching members, said armature having one limb extending across one end of the core and adapted to be attracted thereto, and another limb extending along the said magnetizable member of the structure and adapted to be attracted thereto, the armature being pivoted between the core and the said magnetizable member of the structure apart from the latter so as to be removed with the 'core and coil for purposes substantially as described.

10. A relay structure, a core and coil carried by the structure, means for mounting the said structure whereby the relay as a whole is mounted, and means near the mounting whereby the core and coil may be taken from the said structure without dismounting the latter.

11. A relay of the. character described comprising a. U-shaped magnetizable structure, means for magnetizing said structure, an armature pivoted between the limbs of the said structure and adapted to be operated toward both limbs thereof when said structure is energized, and switching mechanism adapted to be operated by the said armature.

As inventors of the-foregoing we hereunto subscribe our names in the presence of two subscribing witnesses, this 18th day of September, 1908.
